Research On Flipped Class In Junior High School Geometry Teaching

With the deepening of new curriculum reform, stressed that take the student as the main body of learning is higher and higher.More and more scholars and teachers change the traditional pattern of class in order to improve the efficiency of student learning,improve the students' enthusiasm and initiative. Flipped class emergence fits the student as the main feature. It has received the attention of scholars and teachers from all over the world since its advent,people also began to explore different flipped class. And under the background of it, these instructional design that can make teaching contents more scientific and reasonable has become a hot topics in the study.This study not only adopts literature research, comparative studies, interviews and other methods to contrast the traditional class, the teaching situation of flipped class, the current situation of junior high school students in learning geometry, the present situation of Geometry teachers' classes and its existing problems,but also reflect the teaching mode of flipped class at home and abroad and its development in our country. On this basis,design the teaching model framework of flipped class in junior high school geometry, and turn it in practice with the examples of "the Pythagorean theorem ".Therefore, this study is divided into four parts,The first part is the theoretical research part, that is, the first and second chapter of this paper, mainly expounds the research background, this paper studies the purpose, significance, the present situation of the domestic and foreign related research, definition of related concepts, and turn the classroom theoretical basis and practical significance.The second part is the investigation and study part, the third chapter of this paper, mainly interview taught mathematics teachers of junior high school geometry nine and using the method of stratified sampling for 30 students talk investigation.The third part is the part of design research, as the fourth chapter of this paper, mainly from the junior middle school geometry flip classroom design idea, basic structure and process, attention should be paid to the problems in the evaluation and implementation.The fourth part is practice research part, as the fifth chapter of this article, mainly according to the design research part, taking an example of "the Pythagorean theorem" to flip the classroom teaching design, and implementation in the practical teaching of the teaching design.This study argues that flipped class construct the teaching process to a certain extent,set the absorption process of knowledge before the class and put the internalization process of knowledge inside the class. In the flipped class, the role of the teacher changed from the knowledge "teacher" to "guider" and the student from "passive" to "active", in the process of "reverse" compared with traditional teaching, students complete the new knowledge learning process. But the teaching mode of flipped classes that come from the United States is not perfect, it will has to meet with the problem of fighting against the traditional education and weather there is a real conditions into implement in its development in our country. But the author thinks that "flipped class " still deserve us to draw lessons.We should actively explore in practice, carefully summarize and reflect continuously to improve the effect of flipped class implementation.
